[edk2-platforms][PATCH v2 0/5] Platform/Sgi: Miscellaneous updates

[Pranav Madhu]

Changes since V1:
- Rebase the patches on top of latest master branch

This patch series introduces few miscellaneous updates for Arm's
Reference Design platforms. The first two patches add a template
support for hardware reduced ACPI events. This allows helps the
platform get better compliance coverage with SystemReady test
suite. The third patch adds a build macro for enabling graphics
output via the HDLCD. The fourth patch allow build time control
for CPPC and LPI features on the platform. The fifth patch fixes
StandaloneMM build options for the RD platforms.

[edk2-platforms][PATCH v2 1/5] Platform/Sgi: Enable PrimeCell GPIO

[Pranav Madhu]

The HW-Reduced ACPI model has specific requirements for GPIO
controllers. Arm's reference design Platforms has PrimeCell GPIO
(PL061) integrated in the RoS subsystem to provide GPIO support. Add
GPIO device entry and also add GPIO signalled ACPI event template for
reference.

[edk2-platforms][PATCH v2 2/5] Platform/Sgi: Add GED support

[Pranav Madhu]

Add ACPI Generic Event Device (GED) support for Arm's reference design
platforms. The SP804 dual-timer interrupt is used as the event source
for GED.

[edk2-platforms][PATCH v2 3/5] Platform/Sgi: define the macro ENABLE_GOP

[Pranav Madhu]

From: Thomas Abraham <thomas.abraham@arm.com>

Define and use the global macro ENABLE_GOP to enable the use of the
Graphics Output Protocol (GOP). Enabling this macro allows GOP protocol
to be used for display on the HDLCD controller of the platform. This
macro is set to false by default for the all supported platforms.

[edk2-platforms][PATCH v2 4/5] Platform/Sgi: update _OSC control method to control LPI and CPPC

[Pranav Madhu]

Define and use the global macro LPI_EN and CPPC_EN to enable low power
idle and CPPC support for reference design platforms. Update platform
wide _OSC control method to enable/disable low power idle and CPPC
support based on pcd PcdOscLpiEnable and PcdOscCppcEnable. The pcds
are controlled by the global macros LPI_EN and CPPC_EN.

[edk2-platforms][PATCH v2 5/5] Platform/Sgi: Cleanup build options for StandaloneMM context

[Pranav Madhu]

From: Omkar Anand Kulkarni <omkar.kulkarni@arm.com>

The Arm reference design platforms support only AArch64 mode for
StandaloneMM execution context. So cleanup the existing build options
specified for StandaloneMM.
